Two additional class action lawsuits have been filed in federal courts in Alabama and Arkansas by trucking firm customers charging that Pilot Flying J secretly reduced promised rebates by as much as $5 million on diesel fuel purchases.

Like an earlier lawsuit by a Georgia trucking firm, the two new lawsuits repeat allegations spelled out in an FBI search warrant affidavit that described a widespread conspiracy to cheat trucking companies who weren’t paying close attention. The affidavit includes transcripts of secretly recorded meetings of Pilot sales executives in which they joked in expletive-laced language about the rebate scheme.

The Arkansas lawsuit was filed by National Trucking Financial Reclamation Services. The other was filed Thursday in Alabama by W.T.W. Enterprises and its owner Charles E. Winborn. The Alabama company charges that the rebate skimming scheme cost trucking firms in excess of $5 million. The suit charges breach of contract and violations of Tennessee’s Consumer Protection Act.
